AngelMed Guardian System Aims to Predict Heart Attacks

Angel Medical Systems out of Shrewsbury, New Jersey has begun a Phase II clinical trial of the company’s coronary monitoring system, the AngelMed Guardian. The package includes an implantable monitor, with a lead stretching into the heart, that watches for ST changes in the ECG electrical signal. This unit communicates via Bluetooth with a pager-like device worn by the patient that signals for when it predicts a possible MI onset.

IMD (Implantable Medical Device):
An implanted device which is designed to detect, analyze and store the patient’s electrogram waveforms and other crucial heart-signal data. The IMD vibrates to warn the patient of alarms and alerts.
EXD (External Device):
A hand-held telemetry device that is engineered to warn the patient of alarms and alerts via beeps and flashing LEDs. The EXD is also used for communication between the Programmer and the IMD; transmitting vital cardiac information from the IMD to the Programmer.
Programmer:
A workstation used by the physician to configure the IMD and, when desired, retrieve data from the IMD. It uses the EXD plug-in and long range telemetry technology to communicate with the patient’s IMD.
